CIRCLE-SWITCH FOR SPECIFICATION forming part of Letters GALvANlc BATTERIES.

Patent No. 274,452, dated March 20, 1883.

Application filed August 14, 1852. (No model.)

To all whom tt may concern Be it known that I, HENRY LOWE, ot' Brooklyn, in the county ot Kings and State ot' New York, have invented a new and uset'ul Improvenient in Oircle- Switches for Galvanic Batteries,ofwhieh the following is a full, clear, and exact description.

Reference is to he had to the accompanying drawings, forming a. part of this specification, in which similar letters of reference indicate corresponding parts in both the tigures.

Figure 1 is a plan view ot' my improvement, part ot' the connecting-wires being removed. Fig. 2 is a sectional elevation oi' the same, taken through the line 0c, Fig. 1.

rlhe object ot' this invention is to promote convenience in controlling the power ot' galvanic batteries, when used for remedial pur poses, in such a manner that a stronger or weaker current can be used, as may he required.

lhe invention consists in a circle-switch for galvanic batteries, constructed with an insulated annular conducting-plate surrounding a circle of insulated plates and connected with one of said plates by an adjustable plug, and with another of said plates by conductingwires and a switch-arm, the said plates being connected with the cells ot' a battery by conducting-wires, whereby any desired number ot' battery-cells, and from any desired part ot' the battery can be included in the circuit, as will be hereinafter fully described.

A represents a galvanic battery, which may be formed of any desired number ot' cells, B. In the`drawings the battery is represented as being' formed of thirty-two cells, the negative pole ot' each cell, exceptthe first and last, being connected' with the positive pole ofthe adjacent cell by a conducting-wire, O. Each of the wires O, except the one connecting the iirst and second cells, is connected by a conducting-wire, D, with one of a series ot' conducting-plates, E, the iirst and last plates of the series being excepted. rlhe tirst plate ot' the series is connected with the positive pole of the tirst cell B by a conductingwire, D, andthe last plate of the series is connected with the negative pole of the last cell B by a conduct ing-wire, D2. The plates E are arranged in a circle, as shown in Fig. 1, and are insulated from each other and from the stand F, to

| which they are attached. The circle of insuductingplate, G, which is'insulated from the plates E and from the stand F, to which it is attached. .The plate G is placed at such a distance from the plates E that a connection can be vformed between it and either of the said plates E by a plug, Il, introduced between the adjacent edges ot' the said plates G E.

lis the switch-arm, which is pivoted to a conducting-support, J, attached to the stand F at the center ot' the circle ot' plates, E, the said switelrarm being made ol" such a length as to reach to the said plates E, so that it can be brought into contact with either ot' the said plates E when desired. The switch-arm I is provided with a. non conducting handle, K, for convenience in moving it.

With the condacting-support J is connected the end ot' a condueting-wire, L, and with the ring-plate Gr is connected the end ot' another conducting-wire M, so that the electric circuit can be closed by bringing the said wires L M into connection. lhe wires L M are designed to be provided with handles N, to he grasped by the patient, or with other electrmles, to be applied to any part of'l the patients body through which it may be desirable to send an electric current. \Vith this construction, by adjusting the plug l1 or the switch I any de sired number ot' cells B can be included inthe circuit, and an electric current ot' any desired power can be obtained.

In the arrangement shown in Fig. 1 the plug` H isplaced between the lirst plate E ot' the series andthe ring-plate G, and the switcharm I is placed upon the eighth plate E, so that the currentot'electricity will pass through eight cells l5, along` the eighth wire D to the eighth plate E, along` the switch-arm I, conducting-support J, and wire L to the patient, back through the wire M, annular plate G, the

to the tirst cell B, completing the circuit.

By adjusting the plug lland the switch-arm I any desired number of cells D can be used, and the said cells can he taken in any desired part of the battery, so that it' any cell B or connecting-wire D should get out of order, the cells upon either side ot' the said cell or wire can be used.

lated plates E is surrounded by a ring conplug H, the iirst plate E, and the tirst wire D'.

I am aware that a battery for therapeutic purposes, consisting of two switches, insulated the one from the other, and adapted to rotate yaround a common center, and independently connected with the wires or opposite ends ot' the wire by which the circuit is completed, and arranged to travel over a circuit breaker and closer, formed of insulated conductors, that connect each with a separate cup or oups oi' the battery, whereby any desired number of oups may be brought into connection, has heretofore been employed, and I therefore lay no claim to suoli invention, my invention being www@ confined to the construction and arrangement of parts pointed out in the claim.

Having thus described my invention, I claim as new, and desire to secure by Letters Paten tln a circular switch for galvanic batteries, the combination, with the circular series, of insulated plates E, annular insulated plate G, plug H, switch-arm I, and Wires D U M L, substantially as shown and described.
